could you please review the following small webrev:
It not only fixes bug 8026964 on AIX, but is changes the general way
of how to compute BOOT_RTJAR.
With the new solution, BOOT_RTJAR is computed right from the system
property 'sun.boot.class.path'. The new solution should be more robust
and more portable as it doesn't depend on the name of the jar file
which contains the boot classes and it also doesn't depend on the fact
that all these classes are located in a single jar file.
In order to avoid build warnings, I've taken extra care to remove jar
files and paths from the 'sun.boot.class.path' output which do not
exist (e.g. jfr.jar is not available in an OpenJDK build but appears
in 'sun.boot.class.path' anyway - maybe this is another bug that
should be fixed; also jre/classes appears in 'sun.boot.class.path'
although it is not present in the file system - maybe we should fix
that as well).
If we are building on Windows, I convert the content of
'sun.boot.class.path' to Unix form to avoid problems with the FIXPATH
utility. Later, during the build, FIXPATH will convert the path list
back to Windows form.
I've tested the new Solution on Linux, Windows, Solaris and AIX and
couldn't find any problems.
I would like to put this into the ppc-aix-port/stage repository but as
this is a general fix and if you'd like to, it would be also OK if
you'd push it right to the build repository.
Thank you and best regards,
